The script will automatically install required NuGet packages (Dapper and Newtonsoft), invoke SqlServerSchemaReader/PgsqlSchemaReader to read all your tables, columns, indexes, primary keys, foreign keys.Execute the PowerShell script RefreshSqlServerSchema.ps1 or RefreshPgsqlSchema.ps1.Edit the connection string and paths in RefreshSqlServerSchema.csx or RefreshPgsqlSchema.csx.Copy the files from MSSQL or PostgreSQL subfolders into any folder in your project (set the CS files to NOT be part of your build).There are some helper Powershell (PS1) files which download/install the required NuGet packages, locate the CSI (C# REPL), and invoke CSX scripts which invoke the CS files. Some developers may prefer to embed this script into their development/build process (without using the precompiled tool and without creating a new project just for that). There are many CodegenCS templates available - they will read this JSON schema and will generate code based on your Database Schema.Ī very basic template (to generate simple POCOs) can be invoked using codegencs command-line tool.Ĭodegencs simplepocogenerator AdventureWorks.json -Namespace=MyProject.POCOsįor more options use codegencs simplepocogenerator -? or check out Simple POCO documentation Usage (alternative method using Powershell) Generate the POCOs (or any other Template) If you need to modify this utility (or port it to another database provider), please check DbSchema.Extractor source code. This utility can be invoked using codegencs command-line tool.Ĭodegencs extract-dbschema postgresql "Host=localhost Database=Adventureworks Username=postgres Password=MyPassword" AdventureWorks.jsonĬodegencs extract-dbschema mssql "Server=MYSERVER Database=AdventureWorks User Id=myUsername Password=MyPassword" AdventureWorks.jsonĬodegencs extract-dbschema mssql "Server=MYSERVER Database=AdventureWorks Integrated Security=True" AdventureWorks.json Ensure you have dotnet-codegencs tool installedĭotnet tool install -g dotnet-codegencs 2. (DbSchemaExtractor)Ĭ extracts (reverse engineer) the schema of relational databases into a JSON schema.Ĭurrently it supports MSSQL (Microsoft SQL Server) and PostgreSQL.īasically it contains classes to represent the Database Schema (tables, columns, indexes, primary keys, foreign keys), Schema Reader classes (SqlServerSchemaReader or PgsqlSchemaReader) to read the Schema from a MS SQL Server or PostgreSQL database. Overall: DbSchema Pro is an excellent tool for the price. Cons: Free version is really only for evaluation purposes. Generate important documentation from the tool. This page is only about this specific utility - if you're looking for main library, utilities (e.g. Synchronize between database and model, forward and reverse engineer.
